如何为pandas数据帧中索引和列的“交集”指定名称？

intersection = df.columns.intersection(df.index)

df = df.rename_axis({"Intersection": intersection}, axis=1)

import pandas as pd

# 创建一个示例数据帧
data = {'A': [1, 2, 3], 'B': [4, 5, 6], 'C': [7, 8, 9]}
df = pd.DataFrame(data, index=['X', 'Y', 'Z'])

# 获取索引和列的交集
intersection = df.columns.intersection(df.index)

# 为交集指定名称
df = df.rename_axis({"Intersection": intersection}, axis=1)

print(df)

   A  B  Intersection
X  1  4             7
Y  2  5             8
Z  3  6             9
